When it comes to seafood, particularly raw lobster, the colour can be an indicator of its freshness and quality. However, not everyone is aware of the correct colour that raw lobster should be. The confusion often arises due to various factors such as the lobster’s diet, habitat, and even the cooking method. In this article, we will delve into the world of raw lobster and explore the ideal colour it should have, along with other essential information to help you make informed decisions when purchasing or consuming this delicious crustacean.
Introduction to Lobster
Lobster is one of the most sought-after seafood delicacies worldwide, prized for its succulent flesh and rich flavour. It belongs to the family Nephropidae and is found in oceans across the globe, with the American lobster (Homarus americanus) and the European lobster (Homarus gammarus) being the most common species consumed. The colour of a raw lobster can vary, but there is a specific range that is considered optimal for freshness and quality.
Understanding Lobster Colour
The colour of a raw lobster is primarily influenced by the presence of a pigment called astaxanthin, which is responsible for the red, orange, or yellow hues. However, when lobster is raw, this pigment is not as visible, and the colour appears more subdued. A raw lobster typically has a greenish-brown to bluish-brown colour, with the exact shade depending on factors such as diet, age, and environment. It’s essential to note that the colour of a raw lobster can also be affected by the level of oxygen in the water, with lobsters from well-oxygenated waters tend to have a more vibrant colour.
Factors Influencing Lobster Colour
There are several factors that can influence the colour of a raw lobster, making it challenging to pinpoint a single ideal colour. These factors include:
- Diet: Lobsters that feed on a diet rich in astaxanthin, such as algae and crustaceans, tend to have a more intense colour.
- Habitat: Lobsters living in areas with high levels of oxygen and nutrients tend to have a more vibrant colour.

What is the typical colour of raw lobster?
The typical colour of raw lobster is a blend of brown and grey, with a slightly greenish tint on the shell. This is due to the pigments present in the lobster’s shell, which are responsible for its distinct colouration. The brown and grey hues are a result of the combination of melanin and other pigments, while the greenish tint is caused by the presence of a pigment called astaxanthin. Astaxanthin is a carotenoid pigment that is found in many crustaceans, including lobsters, and is responsible for their characteristic colour.
It’s worth noting that the colour of raw lobster can vary slightly depending on factors such as the lobster’s diet, age, and environment. For example, lobsters that are fed a diet rich in astaxanthin may have a more intense greenish colour, while those that are older or have been exposed to certain environmental stressors may have a more muted colour. However, in general, raw lobster is expected to have a brownish-grey colour with a greenish tint, and any significant deviations from this colour may indicate that the lobster is not fresh or of good quality.
Why do some raw lobsters appear more vibrant in colour than others?
The vibrancy of a raw lobster’s colour can be influenced by several factors, including its diet, water quality, and overall health. Lobsters that are fed a diet rich in carotenoid pigments, such as astaxanthin, may have a more intense colour than those that are fed a diet lacking in these pigments. Additionally, lobsters that are raised in clean, well-oxygenated water may have a more vibrant colour than those that are raised in poorer conditions. This is because the quality of the water can affect the lobster’s ability to absorb and process the pigments that contribute to its colour.
In some cases, the vibrant colour of a raw lobster may also be due to the presence of other pigments or compounds that are not naturally occurring in the lobster’s shell. For example, some lobster farms may use feed supplements that contain synthetic pigments to enhance the colour of their lobsters. While these supplements are generally considered safe for human consumption, they can affect the natural colouration of the lobster and may not be desirable for consumers who are looking for a more natural product. As a result, it’s worth checking with the supplier or farmer to determine whether the lobsters have been fed any colour-enhancing supplements.
Can the colour of raw lobster indicate its freshness?
The colour of raw lobster can be one indicator of its freshness, but it is not the only factor to consider. A fresh raw lobster is expected to have a brownish-grey colour with a greenish tint, as mentioned earlier. If the lobster has a significantly different colour, such as a pale or washed-out appearance, it may indicate that the lobster is not fresh or has been stored improperly. Additionally, if the lobster has a strong, unpleasant odour or feels soft and mushy to the touch, it is likely past its prime and should be avoided.
However, it’s also important to note that the colour of raw lobster can be affected by factors such as handling and storage, and may not always be a reliable indicator of freshness. For example, if a raw lobster is exposed to air for too long, it may begin to turn a pale yellow or white colour, even if it is still fresh. Similarly, if a raw lobster is stored in a way that causes it to become dehydrated, it may develop a dull or wrinkled appearance, regardless of its actual freshness. As a result, it’s always best to consider the colour of raw lobster in combination with other factors, such as its texture, odour, and overall appearance, to determine its freshness and quality.
How does the colour of raw lobster change when it is cooked?
When raw lobster is cooked, its colour changes dramatically. The brownish-grey colour with a greenish tint that is characteristic of raw lobster gives way to a bright red or orange colour that is more intense and vibrant. This colour change is due to the denaturation of the proteins in the lobster’s shell, which causes the pigments to become more visible and intense. The exact shade of red or orange that the cooked lobster turns will depend on the cooking method and the degree of doneness, but in general, cooked lobster is expected to have a bright, fire-engine red colour.
The colour change that occurs when raw lobster is cooked is not just cosmetic; it is also an indicator of the lobster’s doneness and safety. Cooked lobster should be opaque and firm to the touch, and should have a bright red or orange colour that is evenly distributed throughout the meat. If the lobster is undercooked or raw in the centre, it may still have a translucent or pale colour, and should be avoided due to the risk of foodborne illness. As a result, it’s always important to cook lobster thoroughly and to check its colour and texture before serving to ensure that it is safe and enjoyable to eat.
Are there any health risks associated with eating raw lobster that has an unusual colour?
Eating raw lobster that has an unusual colour can pose a health risk, as it may indicate that the lobster is not fresh or has been contaminated with bacteria or other pathogens. Raw lobster that has a pale, washed-out colour or an off smell may be a sign of spoilage, and should be avoided due to the risk of foodborne illness. Additionally, raw lobster that has been exposed to certain environmental toxins or pollutants may have an unusual colour or appearance, and should be avoided due to the potential health risks.
In general, it’s always best to err on the side of caution when it comes to eating raw lobster, and to choose lobsters that have a fresh, natural appearance and smell. If you are unsure about the freshness or quality of a raw lobster, it’s best to cook it thoroughly before eating to minimize the risk of foodborne illness. Additionally, if you experience any symptoms such as nausea, vomiting, or diarrhea after eating raw lobster, you should seek medical attention immediately to rule out any potential health risks.
Can the colour of raw lobster be affected by environmental factors?
Yes, the colour of raw lobster can be affected by environmental factors such as water quality, temperature, and exposure to light. For example, lobsters that are raised in waters with high levels of pollution or sediment may have a duller or more muted colour than those that are raised in cleaner waters. Additionally, lobsters that are exposed to high levels of ultraviolet light may have a more intense colour than those that are raised in darker or more shaded areas. Temperature can also affect the colour of raw lobster, as lobsters that are raised in warmer waters may have a more vibrant colour than those that are raised in cooler waters.
In some cases, environmental factors can also affect the distribution and intensity of the pigments that contribute to the colour of raw lobster. For example, lobsters that are raised in areas with high levels of algae or other microorganisms may have a more intense greenish colour due to the presence of pigments such as astaxanthin. Similarly, lobsters that are exposed to certain environmental stressors, such as changes in water temperature or chemistry, may have a more muted or pale colour due to the disruption of the pigments that contribute to their colour. As a result, the colour of raw lobster can be an important indicator of the environmental conditions in which it was raised, and can provide valuable information about the lobster’s quality and freshness.
